engine SKODA ROOMSTER 2013 1.G Repair Manual

WARNING“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
CAUTION
On vehicles with the START/STOP system, the pole terminal of the charger must
not be connected directly to the negative terminal of the vehicle battery, but only
to the engine earth » page 188, Jump-starting in vehicles with the START-STOP
system .
Note
We therefore recommend that vehicle batteries be rapid charged by a specialist
garage.
Disconnecting or reconnecting
First read and observe the introductory information and safety warn-ings
on page 168.
The following functions are initially deactivated or are no longer able to operate
faultlessly after the vehicle battery has been disconnected and reconnected.

tion systemSetting the clock» page 12Data in the multifunction display are deleted.» page 13
Note
We recommend having the vehicle checked by a specialist garage in order to en-
sure full functionality of all electrical systems.
Replacing
First read and observe the introductory information and safety warn-
ings
on page 168.
When replacing a battery, the new vehicle battery must have the same capacity,
voltage, amperage and be the same size. Suitable vehicle battery types can be purchased from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be dis-
posed of in accordance with national regulations.

Automatic load deactivation
First read and observe the introductory information and safety warn-ings
on page 168.
The vehicle voltage control unit automatically prevents the battery from discharg-
ing when the battery is put under high levels of strain. This may be noticed from
the following.
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where necessary, large convenience consumers such as seat heaters and rear
window heaters have their power limited or are shut off completely in the event
of an emergency.
CAUTION
■ Despite such intervention by the vehicle electric system management, the vehi-
cle battery may be drained. For example, when the ignition is switched on a long
time with the engine turned off or the side or parking lights are turned on during longer parking.■
Consumers that are supplied via a 12-V power socket can cause the vehicle bat-
tery to discharge when the ignition is switched off.
Note
Driving comfort is not impaired by consumers being deactivated. The driver is of-
ten not aware of it having taken place.
171Inspecting and replenishing

WARNINGObserve the following instructions for lifting the vehicle.■If the wheel has to be changed on a slope, first of all block the opposite
wheel with a stone or similar object to prevent the vehicle from unexpectedly
rolling away.■
Secure the base plate of the lifting jack with suitable means to prevent pos-
sible moving. A soft and slippery ground under the base plate may move the lifting jack, causing the vehicle to fall down. It is therefore always necessary to
place the lifting jack on a solid surface or use a wide and stable base. Use a non-slip base (e.g. a rubber foot mat) if the surface is smooth, such as cobbled
stones, tiled floor, etc.
■
Only attach the lifting jack to the attachment points provided for this pur-
pose.
■
Always raise the vehicle with the doors closed.
■
Never position any body parts, such as arms or legs under the vehicle, while
the vehicle is raised with a lifting jack.
■
Never start the engine when the vehicle is raised – risk of injury.
CAUTION
■ The tightening torque specified for the wheel bolts for steel and light alloy
wheels is 120 Nm.■
The anti-theft wheel bolt or the adapter can be damaged if the wheel bolts are
tightened too much.
Note
■ The anti-theft wheel bolt set and adapter can be purchased from a ŠKODA Part-
ner.■
The national legal requirements must be observed when changing a wheel.

WARNING (Continued)■The non-insulated parts of the terminal clamps must never touch each other
– there is a risk of short circuit.■
The jump-start cable connected to the positive terminal of the battery must
not come into contact with electrically conducting parts of the vehicle – there
is a risk of short circuit.
■
Do not clamp the jump-start cable to the negative terminal of the dis-
charged battery. There is the risk of detonating gas seeping out the battery
being ignited by the strong spark which results from the engine being started.
■
Route the jump-start cables so that they cannot be caught by any rotating
parts in the engine compartment.
■
Do not bend over the battery – there is a risk of caustic burns.
■
The vent screws of the battery cells must be tightened firmly.
■
Keep any sources of ignition (naked flame, lit cigarettes, etc.) away from the
battery – there is a risk of explosion.
■
Never jump-start vehicle batteries with insufficient acid levels – risk of ex-
plosion and chemical burns.
CAUTION
■ There must not be any contact between the two vehicles otherwise current
may flow as soon as the negative terminals are connected.■
The discharged battery must be properly connected to the system of the vehi-
cle.

Introduction
This chapter contains information on the following subjects:
Front towing eye
189
Rear towing eye
189
Vehicles with a tow hitch
189
Vehicles with manual transmission may be towed in with a tow bar or a tow rope
or with the front or rear wheels raised.
Vehicles with automatic transmission may be towed in with a tow bar or a tow
rope or with the front wheels raised. If the vehicle is raised at rear, the automatic
gearbox is damaged!
A tow bar is the safest way of towing a vehicle and also minimises any shocks.
Only use a tow rope if a suitable tow bar is not available.
The following guidelines must be observed when towing.
Driver of the tow vehicle›Release the clutch particularly gently when starting off or depress the accelera-
tor particularly gently if the vehicle is fitted with an automatic gearbox.›
On vehicles with a manual transmission, only push down on the accelerator pedal once the rope is taught.
The maximum towing speed is 50 km/h.
Driver of the towed vehicle
›
Switch on the ignition so that the steering wheel is not locked and so that the turn signal lights, horn, windscreen wipers and windscreen washer system can
be used.
›
Take the vehicle out of gear or move the selector lever into position N if the ve-
hicle is fitted with an automatic gearbox.
Please note that the brake servo unit and power steering only operate if the en-
gine is running. If the engine is not running, significantly more physical force is re-
quired to depress the brake pedal and steer the vehicle.
If using a tow rope, ensure that it is always kept taught.
CAUTION
■ Do not tow start the engine – there is a risk of damaging the engine and the
catalytic converter. The battery from another vehicle can be used as a jump-start
aid » page 186 , Jump-starting .■
If the gearbox no longer contains any oil because of a defect, your vehicle must
only be towed with the driven wheels raised clear of the ground or on a special
breakdown vehicle or trailer.
■
The vehicle must be transported on a special breakdown vehicle or trailer if it is
not possible to tow in the vehicle in the way described or if the towing distance is greater than 50 km.
■
To protect both vehicles when tow-starting or towing, the tow rope should be
elastic. Thus one should only use plastic fibre rope or a rope made out of a simi-
larly elastic material.
■
While towing, take care to avoid impermissibly high tensile forces or jerky loads.
There is always a risk of excessive stresses and damage resulting at the points to
which you attach the tow rope or tow bar when you attempt to tow a vehicle
which is not standing on a paved road.
■
Attach the tow rope or the tow bar to the towing eyes » page 189
or » page 189 to the detachable ball head of the towing equipment » page 117 .

Some manual skills are required to change a bulb. For this reason, we recommend
having bulbs replaced by a specialist garage or seeking other expert help in the
event of any uncertainties.
› Switch off the ignition and all of the lights before replacing a bulb.
› Faulty bulbs must only be replaced with the same type of bulbs. The designa-
tion is located on the light socket or the glass bulb.
› A stowage compartment for replacement bulbs is located in a plastic box in the
spare wheel or underneath the floor covering in the boot.WARNING■ Accidents can be caused if the road in front of the vehicle is not sufficiently
illuminated and the vehicle cannot or can only be seen with difficulty by other
road users.■
Always read and observe the warnings before completing any work in the
engine compartment » page 159, Engine compartment .
■
Bulbs H7 and H4 are pressurised and may burst when changed - there is a
risk of injury. We therefore recommended wearing gloves and safety glasses
when changing a bulb.
CAUTION
■ Do not take hold of the glass bulb with naked fingers (even the smallest
amount of dirt reduces the working life of the light bulb). Use a clean cloth, nap-
kin, or similar.■
When removing and installing the number plate light and tail light make sure
that the paintwork of the vehicle and the tail light are not damaged.
Note
■ This Owner's Manual only describes the replacement of bulbs where it is possi-
ble to replace the bulbs on your own without any complications arising. Other bulbs must be replaced by a specialist garage.■
We recommend that a box of replacement bulbs always be carried in the vehi-
cle. Replacement bulbs can be purchased from ŠKODAOriginal Accessories.
■
We recommend having the headlight settings checked by a specialist garage af-
ter replacing a bulb in the main or low beam.
■
Visit a specialist garage if an LED is faulty.
